  1. I'm very much confined to a small space that I can truly call 'mine' and which only I use. So I'm often looking around the place and wondering what I can do, or what can I modify, to facilitate an indoor grow. I'm a very moderate user compared to many, so I don't necessarily need enormous yields to keep my going - usually only one or maybe two small vape chambers an evening. I came across some info this week regarding 'micro stealth growing', which I'm sure I was aware of but had perhaps forgotten. I think this sounds exactly what I need. A guy on the youchoob created a little micro setup inside an Ikea Hällan metal cabinet, which are about 40x40x75 or something. Really small, but possible for one plant. Plus being metal, he could attach most of the equipment inside with magnets which was pretty cool. Made it really easy to move the little portable fan, for example. It had strips of LED lighting, two on either side, and four smaller ones in the top. The results were pretty amazing tbf (all the lower site buds were still hefty since light had gotten to all the plant). It had a padlock hole on the door which was a nice touch, although not so stealthy with a padlock on the front! So I think I may go this route, then, if I decide I'm going to go for it. Has anyone else ever had experience with making something like this? I know it's a bit restrictive with the small size, but I really don't mind that.
  2. Hi to all stealth cab builders. I've always like the idea of hidden grows and ordinary household cupboards are perfect for bonsai mum/mini nurseries. Most have issues with noise and light leaks, some build boxes to last a few grows, I wanted to build a grow box that would outlast me. Ideally, I'd just go out and use a secret garden dp90, which I've used in the past behind a wardrobe curtain (hidden), but the new house has no such space behind a curtain so I was forced to use the hidden in plain sight tactics. With a tent, it's pretty obvious what's going on, and I wanted my growing to be 100% hidden, so turning ordinary household furniture was a natural choice. The IKEA box worked well (and still does) but it's on its last legs, as with MDF and moisture, it's all bubbled and rotting from within. For the price of another new IKEA box, I bought a solid wooden sideboard 94cm x 40cm x 86cm (WxDxH) from Gumtree and went about installing reflective material, light baffles (can't have any light leaks), AC Infinity T4 with 150mm (short) 4" Phresh carbon filter, my original Scope 275 V1 (4x Samsung 3000k strips), and a 5w 8 inch USB fan that's only 1" thick- perfect for pushing air down onto the plants (hanging on bungee cords). All electricity is delivered using 1 discreet cable from behind, and I use a Meross 4 way smart switch inside the box with 'routines' created in an app for lighting and fan schedules. Here's the build. Almost silent, totally light and smell proof. As you can see, I included side lighting strips coz I was curious about the benefits, and 4 scope 275 strips would be overkill for the top. Secret Jardin light baffles-bug screens, you can see they were slightly too big for the duct ending, so I split the plastic and ended up taping them with silver tape. They 150mm. Possibly overkill for passive intakes but can always be blocked, and will pay off on hot days.. Spare Scope 275 V1's split into side/top lighting. This unit is turned down to the lowest setting in the driver - which I believe is 50%, or 137w draw, but that's only a guess.. Always solder the ends to keep them tidy. @DIYLEDUK were generous enough with bolting the strips to the iconic blue heatsinks, but I've found double sided thermal tape to be very strong to attach the strips back to the heatsinks. Tidy at the back, although it'll never be seen. Mylar all round.. Diagonal side lighting strips.. We all love a bit of filter porn (or maybe it's just me? ) And the ultra silent USB fan that I shoved at the top on bungees. It has a small battery, so if the power ever cuts, at least the plants still have a breeze! Not exactly stealth, but had the controller on a few days to make sure it was running ok. Controller is hidden inside now. And here's the finish. Nothing to see here, officers, it's just a TV stand, not a 'drug farm'... Few upgrades to come are a bespoke 3mm acrylic floor to be sealed in with silicone. A waterproof electric grommet for the main power cable out the back, and possibly add a drain in the floor for the runoff and easy watering.
  3. I was thinking of that white lime wash paint and some white netting on the inside. I wonder if anyone tried bubble wraps on top, are they uv permeable? I dont want to loose much benefit of the glass and it seems the limewash already dims the light considerably thx for the tips
  4. I've been out and about a few times over the last week or so, rummaging through the undergrowth as it were, scouting for a potential spot. I think I may have found one. It is pretty close to a well-used dog-walking route, but it is very well concealed, with a shitload of bramble that is way high and would shield from any passing eyes. It needs work, as in I would need to wade into the thick of it and hollow out a little area, but I think it would be possible. There is an easier area just beside it, but I think it is too shady and there is a really good light in the more difficult spot. The only thing that concerns me with it being close to a path, is obviously the whiff-factor. I want to do autos, but are there any strains that perhaps don't chuck up as much? Also, does anyone here use pots rather than direct into the ground? Any reasons for or against?
  5. Hi, I am in the process of insulating the shed in which my tent will be. After that I need to work out the best way to make the 3-in-a-row windows lightproof, so that when I open my tent, the overlooking neighbours won't be treated to a suspicious flood of bright light. Ideally, the solution won't look too weird and attract questions from visitors to our garden, or the last few friends who might even want to peek inside. Theres obfuscating materials inside, so the tent is kind of well hidden, but what to do about the windows? I suppose my best case scenario is mould proof, pencil-pleat, blackout curtains, pinned on the tent end. With a 2.2M length and 1M drop though, I'd probably have to make them myself - which I have no experience in and would probably make a dogs dinner of - or pay a fair bit for a custom made set. I could make a set of box shutters, but that'd be difficult, complicated or expensive. Roller blinds would allow too much spill around the edges. Any good ideas to help with my pauper build? Cheers! Midge
  6. Morning glorious People. After a couple of requests the refrigerator of stealth is here... please feel free to critique or comment on this thread, interestingly it would be an awesome rolling thread If other members growing in refrigerators could add content along the way. Unless I’m totally alone on this one.. After much consideration on how best to hide a grow box in plain sight and looking at different designs and ideas, I decided it was best for me not to hide one. I’m settled on the conclusion that it would be less stressful and easier to access if I didn’t need to hide things or take time accessing locked rooms. I would need to be sufficiently able to produce enough medical marijuana from my personal consumption. That’s the ideal. Very Low cost set up was important along with low cost to run the setup once up and running.
  7. This is probably of no interest at all to most, I guess for a lot of folk with quiet fans and grow rooms inside the house that are tucked out of the way it would be of no use at all. There's bound to be a few other nervy people here though, with less well hidden and noisy grow rooms who have a lot of guests coming through and causing worry about discovery. For me, growing in a garden shed in suburban Manc-land, with lots of people coming in and out of the house and garden during most months of the year, I was getting a bit paranoid about the fan noise coming out of my shed. Yeah I could claim it is just a fan to dehumidify the shed, or whatever but I figured better still not to have to make disingenuous reasons up. I just bought something that is rather handy for reducing my paranoia, a remote control socket switch from Ebay. I am getting a quieter AC Infinity setup once Ledgrowlights.co.uk have them in stock, but for now I am using a cheap and noisy inline black-orchid extractor. For various reasons, I had to put the exhaust outlet on my garden side of the shed. The neighbour's side is totally open to their garden (the shed fills a gap in the hedge / fence boundary). I couldn't put it on that side, because the last thing I need is their anti-drug matriarch or patriarch throwing a fit when my filter starts to die and they start to smell weed. The noise of my fan itself is enough to arouse suspicion once you get within a couple of metres of the exhaust port anyway and they are too nosey to take a simple explanation. There is a lock on the shed, but they could easily access our side and stick their noses in if they wanted and I can't be mithered. Anyway, I got to thinking that a remote control for the socket the fan is plugged into would sort the problem. If we have visitors and they are in the part of the garden my shed is in, I can turn the fan off for a short while until they move away and back on when they are at a safe distance. I work upstairs overlooking my garden, so it is easy to see what is going on and turn the noise off for a short while if required. At the moment I'm using the extractor to keep my drying tent ventilated, so heat build up won't be a problem. Even when the tent is being used for a grow, I use LED lights, so... as long as the fan isn't off for hours, the heat and humidity build up should be fairly insignificant. The remote controlled socket can take up to 3KW of draw through it, so if the idea is of interest to anyone, there're few setups that would be very problematic. I imagine it would be useful for all the noisy parts of a grow room, from a distance - extractor fans, aircon and air-movement fans, to turn them off when you know someone nosey is about The same remote can control up to 3 sockets independently too. I just tested it and it is sound, so sharing in case it solves a problem for someone else. The only risk I suppose is if somebody elses RF frequencies caused the relay in the socket to trigger and the fan shut-off unnoticed. I figure I check the tent often enough that it isn't a problem for me, particularly when I am only using it to dry plants in the dark anyway All the best, Midge.
  8. Im looking for a way to make my old glass greenhouse stealthy from prying eyes. I somehow achieved this by accident last season when I sprinkled baking soda on those windows. I wonder if there is something better that would give the glass the nasty look feeling that would make it less visible to see what is inside, or if the white paint is the only way. Thanks for the help 420 fam
  9. Kindly asking for your advice and critique, Planning my first build. I live in a house share, I have a small bedroom. For space reasons I sleep in one of those kinda bunk beds that only have the top bed so you get floor space underneath etc. My rough Dimensions for growbox under the bed are 70cm / 2.29 ft length 66cm / 2.16 ft width 80cm / 2.6 ft height I plan to make a frame with wooden battens, plasterboard outside then fill with celotex insulation then plasterboard on the inside and paint white or mylar. I did this with heat and noise isolation in mind. My light will probably be a DIY samsung strip light of 100-130 watt. I will obviously need a carbon filter but seeing some inline fan videos they're bloody jet engines. PC fans and the like are widely used I've seen on micro grows but looking on this forum are regarded as no good. I was thinking of getting an AC Cloudline Infinity 6" so I can run on a lower RPM. again I dont know how loud this will be. And I assume I need to be circulating a certain CFM for the carbon to be effective. My top concerns are Noise and smell, but mostly noise. I work and sleep in this room so If it turns out irritating then it'll be a no go. Before I go any deeper into the project I wanted to know whether I'm being realistic. The annoying this is I won't know until I actually buy all the kit as I have no experience. cheers
  10. WELCOME! Id love to say "I'm back" with another micro grow but i have had to make a new account due to stupidly using my old user name on lots of other sites. Not gonna lie, it sucks a bit as i was a active user of the forum about 6 years ago and ran a few grow diaries then but ended up not finishing the threads. Now i come back to do another and realised a new account must be made, which means i lost my subscriber status oh well, start new! So here is what will turn into my diary for my current grow, its been 6 years since my last attempt, and again i'm just fed up of spending a fortune on what i know i can grow at home! Enough chit chat, lets get into it! For this grow i will be using a 92l storage tub, lined with diamond mylar (not very neatly if i do say so myself ), a LED light unit i purchased from a guy online who makes them (holy shit is it bright), inlet fan, exhaust fan pulling through a home made carbon filter box, 6" pots and i will be growing the sweet seed mohan ram using a good amount of low stress training to keep the plants low and bushy! This worked wonders before when growing in PC cases so i'm hoping it will contain them nicely in this box, as the light is a lot more powerful than last time and the pots are bigger so i'm sure they are going to fill the space right up!! I have grown the mohan ram before and its a great plant for small spaces due to the way it stays nice and bushy! i decided i would start the diary today and i have just about finished building the box and the seeds are almost ready for the soil! So first, the box itself! Its a very simple bodge job set up i have pieced together from random cheap bargains online, but considering my last grows were inside PC cases im gonna have way more space to work with! Its not pretty, used lots of hot glue, double sided tape for the mylar application and my trusty knife to cut rough holes for the fans to pull through. Being someone who doesn't do a great deal of building stuff though, i'm pretty happy with how it came out! The 2 fans are just 140mm PC fans, wired onto a 12v 1a power adaptor, took me an hour or so to work it all out last night but its all working now! (The fans wires were marked very weirdly so trial and error took a while to get them paired up right!). The light is a LED unit that the seller says produces 12k lumens of full spectrum light and uses a metal fin design to dissipate the heat. Each LED has 8 reflectors around it too so the light coming off of this bad boy makes the 80w CFL i was using in the PC cases look like a low battery keyring torch. Here is a couple images of the box from the outside! Now that the box is ready, the light is mounted to the top of it i decided to bang 3 seeds into some water! They all cracked nicely over night and then this morning have been put on some wet paper folded over to help them show a good root, then ill be putting them into the soil later tonight or tomorrow morning! Exciting times! I could bang them right in the soil now as they shown a nice start just in the water, but i think ill let them go another 12 hours in the tissue just so i have a good established tail before planting! The idea is going to 18/6 for the whole grow as they are autoflowering. Medium is biobizz all mix, nice and simple, i went with the plant magic last time so i thought id switch it up and try the bizz this time, and i also grabbed their try pack of the 3 organic feeds, veg bloom and topmax! I'm aiming for an OZ per plant dried if i can, then if the smaller 3rd makes much thats just a bonus! as working it out, 2 OZ would last me nicely until i could have another couple of plants ready for the chop on round 2, if this one goes well! The plan was originally just to do 2 plants as space is tight in the box, but i popped 3 seeds in to make sure atleast 2 would germinate, but all 3 are doing great so one will be going into a slightly smaller pot and either joining the other 2 in the box if the space doesn't get to tight, if down the line i start to get short of space then it may well have to be a conservatory girl if it stays nice and small. Not really a lot to add at this point, but hopefully in the next 7 days we'll have some pictures of some girls poking out of the soil and getting started good and proper!
  11. I posted yesterday about my black orchid hybrid flow 4* extractor which is way too noisey for a stealth grow. I came to the conclusion that i would buy loads of polystyrene chips which i could stuff into a box with cut outs along with sound proof adhesive pads completely covering it all, as well as hanging it from all the great info you guys gave. I then came across old threads mentioning the xpelair wac1 controller. I'm willing to spend up to £100 on the extractor setup so could someone please recommend a good fan which i could run practically silently (i mean like silent to the point that you can only lightly hear it in that room only) and controller such as the one mentioned (not sure if it's still used). I'm just gonna return that trash black orchid one, and get a better one. I also heard that its best to get a 5" fan for example on really low as the motor will barely have to work for the space making it silent, any recommendations? Note: i also already have a carboair 50, however it is 4" and i can't return it so i guess i could get an adapter i just don't know where from if i do get a bigger duct size. I'm trying to get the most for my money, and have already spent loads buying wrong ducting and all other kinds of stuff i wont use as i have also learnt i need to get acoustic ducting aswell
  12. So this is for all you urban growers out there. How are you guys hiding your extraction when venting out of the window? Last time around I attached my extraction duct to the radiator behind the curtain and just left the window open. It worked just fine but I'd like to seal off the window with a hole for extraction, giving me better control of temps at different times of year and better protection from smell leaks when opening up the tent. The best idea I've been able to come up with is to cover the entire recess with a layer of hardboard and fit a duct spigot. Obviously the hole where the extraction point sits would be massively obvious from outside. And a house with boarded-up windows looks just as bad. So I thought about buying a made-to-measure wooden Venetian blind to fit the recess. Now I thought about simply fitting the blind in the recess and fitting the board behind it but the slats would be hanging free to jostle in the breeze caused by the extracted air. This led me to the idea of taking the blind apart and attaching them to the board with glue (or something) in an angled up position so nothing could be seen by passers by except an open blind. Sorry for the rambling and I hope this makes sense as I'm working my way through a grinder full. I'd love to hear some ideas. Cost effective ones are better. This idea I've mentioned would cost about 50...
  13. Hello all, Just after a few pointers if possible please. I'm experimenting with a CBD auto strain called dinamed kush, I use CBD oils and i'm genuinely curious in the cultivation of the plant. Needless to say, I'm now treating my little plant like a newborn child! I think she popped on the 18th Feb, making her about 3 weeks old now. From my copious amounts of reading; I think I have over-watered this first plant so i'm just easing off a little now. I maybe over compensated due the humidity only being around 40% (up to 50% for a while after misting). Also trying to increase the humidity, I stood the plants in clay ball pots and fill (most days) with water, taking care to only fill about half way up the tray. I did gently ease out the plant to see the soil, and the roots look a healthy white colour all around the container. The USB fan is just simply intaking air from the open flap at the bottom of the tent and expelling passively it out the vent at the top. I'm just wondering if i'm doing anything obviously wrong (other than over-watering/stunting the growth), and for example when I should move into the final 7litre pot with Canna Terra Pro (mixed with perlite), or when to give her the first diluted grow feed. By the way the second plant is an auto called Charlotte's Angel which has just popped, and I'll treat differently by not watering as much. Here's my set up: 40cm x 40cm x 120cm tent Mars Hydro Reflector 48 300w Dalefoot fine wool seed compost peat-free (using now for seedlings) Canna terra professional (for repotting later) USB powered fan (half speed) Light is roughly 24" from plant P.M.

  14. Hey guys, i've been eyeing this up for a couple of weeks now and can't seem to figure out what im looking at. So I have two closets side by side. One has the immersion heater and the other is empty and houses my grow tent. I currently have an extension lead plugged in to the wall across the corridor from the closet, trailing along the floor and then in to my grow tent. Not Ideal as i keep tripping on it and its not very stealthy. I want to figure out a way of wiring the extension lead inside of the closet utilising the electric pints that are already in there, which appear to be an old house alarm (de-activated) and the immersion controller. Im not very electric-savy so I thought i should ask in here before I blow something up. I've got my grow tent set up in the small empty closet next to the immersion closet. The two closets are side by side. In the immersion closet theres the immersion heater tank, some shelves and the control switch for it on the wall with some grounding wires attached to a copper pipe and some other green (grounding wires also?) wire going through the wall in to my grow closet. Pic below: The two white wires coming out the bottom of the box go down to the water heater and are connected straight in to its heating elements. Its the green and yellow wires that go through the wall that have my attention as something to tap in to for an extension plug outlet. This is the old house alarm panel on the opposite side that wall and where that green wire leads to: Having a hard time figuring out whats what in here and how i would even go about wiring an extension cord on to any of this....Anyone have any ideas? Im completely stumped here!
  15. Just signed up . Contemplating a 2020 grow. First time grower here, well actually it's a second time, my first attempt resulted in being caught entering/leaving and the plants were destroyed a week after planting. I'm struggling to find good plots because it seems that any natural area (i.e. not a field or urban area) here is criss-crossed with walkers' paths. I have found some potential plots, but they are about 10m-20m from a path. Is this stupid? I am thinking about strains such as Durban Poison and Passion #1 + some autos or semi-autos I have not decided on. I heard Durban doesn't smell that strong so my chances might be higher than if it were a Skunk #1. What are the odds that I can make it to harvest? I may keep the plants spread out, even lone plants, so that I can afford some discoveries/losses. I'll keep looking for better and better plots, but there is basically no expansive woodlands or scrublands here without paths criss-crossing them. Thanks

  19. I am setting up a grow tent (50 x 100 x 200), which is relatively small, and have some questions about the exhaust and intake fans. 1. Does it make any difference if I place the exhaust fan inside the tent, or outside the tent with ducting running inside? 2. Does it make any difference if I place the carbon filter at the 'blow' end of the duct system, outside of the tent, so the fan is sucking air directly from the volume inside the tent? 3. How noticeable is it to aim the exhaust duct at an open window (with no direct line of sight)? Will it create a noticeable, strange noise that would get attention?

  21. hi all. so ive been reading a lot about COBs and my interest is piqued. Clearly LEDs - COBs in particular - are finally starting to rival/take over from HIDs in terms of yield and spectrum (if not yet price) but what really interests me is a different kind of potential which I think they might have. LEDs dont need the kind of bulky reflectors an HPS bulb does, so it should, theoretically, be possible to hide one behind a standard domestic ceiling light fitting. (even if it has to be a bespoke built unit) also they can be dimmable, so the idea (the dream!) is to do this in a bathroom/wetroom and rig the door to trigger the dimer function when the handle is turned, so that it looks only as bright as a normal domestic light when the door is opened. if popo ever come looking all they get is a couple of (monster) plants in a bathroom with no sign whatsoever of any grow equipment at all. (C.F. would be housed behind dummy bathroom extractor unit and nutes would be coming in through the shower head from a second water tank (res) in the attic ... run to waste in coco and kick back. "they just grew like that officer" I know how to do the rest of it but im not a spark. i know it has to be possible so my technical question to anyone who really understands the electronics is ... 1) how hard would it be to remote trigger the dimmer function? can it be done realistically? and 2) what type of opaque/ 1 way glass would you use in the fitting to minimise any loss of lumen intensity from the COB? Hope that makes sense, thanks in advance for any help or research resources, stay safe. cheers MM
  22. Hi there, a hilariously simply tutorial for y'all - how to do e-liquid real good real easy. Starting material - high quality vac purged BHO - rosin never matches closed loop cryo bho for terps - ever. here is 0.52g, placed in a 60ml glass jar - this gives a small surface area on the bottom so not much space for material to spread around too much. Next, using a syringe and 21g needle, draw up 0.5ml c8 caprylic acid (refined portion of MCT oil), or alternative liquidiser (most are toxic). Then, add the liquid to the shatter..... Then place on a plate warmer for enough time for solution to hit between 27-30ºC - the higher you go the more terps you lose.... on the warmer with an RSO run... After the first 4 minutes, pre mixing - I work the timing out by pre-testing with 1ml mct oil and a food thermometer - I timed 4 minutes before my oil hits 27ºC when placed on warmer - so that is my heating timing before I remove my jar and use my dab tool like a pestle - grinding and dissolving the shatter.... Keep repeating the cycle, take your time, and you will very quickly have - Vape liquid! Use the same syringe to draw it back up..... Then dispense into your chosen cartridge(s) - cart on the left is designed for thickest of distillates and has a high pull rate - lovely for a strong blast. Cart on the right is the new full ceramic system - fucking devine. unbelievably good. so worth the wait. shits all over the c-cells even... In awe If you are running cheaper wick based systems - use a 2:1 ratio of liquidiser to shatter, it'll run better. Thick liquids need large holes and ceramic coils for flow rate. always run your vape at 6-8w, no higher! If you have the money, a lab centrifuge is amazing for mixing this liquid at room temps - I tested a run of sauce and bho liquids thanks to a sneaky phd professor pal of mine at the university - they ALL mixed perfectly at 18ºC In my experience, the better quality the extract, the easier it is to dissolve - the more I've winterized, de waxed, and vac purged/ flipped my stuff, the easier it is to dissolve... So, cold temperatures are key folks. Any questions/criticisms just hit me up here. Peace OOOOOOTTTTTTTTTT X
